Berries
Fruit and vegetables are packed with nutrients, but they also provide a source of antioxidants that can help destroy free radicals in the body, which can cause cell damage. In particular, berries contain flu-fighting antioxidants called flavonoids.
Berries are often used for treating respiratory issues like the flu and contain high amounts of vitamin C and anthocyanidins (the same compounds found in red wine). This is because these compounds increase the production of white blood cells to fight off the infection.
While there have been no studies on eating berries to fight off the flu, there have been many on the health benefits of berry consumption in general. It would only make sense that if eating berries can help prevent lower respiratory infections, eating them during an active infection could also help you get back to health faster.
